-App1ication filed January 6, 1914. Serial No. 810,598..

To all 10h am it may concern:

Be'iti'known that I, DAVID M. PERINE, a

citizen of the United States of America, re-, siding in the city, county, and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a true and exact description,

reference being had to the accompanying the manufacturing and temperingof the latter.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a. part of this specification. For a better understanding of the invention, however, and of the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described one form in which my invention may be embodied. Of the drawings: Figure 1 is a plan view of a sheet metal blank from which the body of the holder may be made: Fig. 2 is a plan view of the sheet metal blank from which the blade clamp may be made: Fig. 3 is a plan view of the blade; Fig. 4 is a perspective view of the holder, opened to permit the insertion or removal of a blade; and Fig. 5 is a view partly in section of'the holder with a. blade clamped therein.

My razor blade holder comprises two parts-a frame or body member A; and a blade clamp B. The frame member A comprises a handle portion A and a neck A connecting the handle portion to the blade supporting portion A". The blade supporting portion A is formed at 1ts free edge with guard fingers A, and at each end of the bed or supporting surface for the blade with :1 lug or ear A and a lug or ear A,

which extend perpendicular to the bed or supporting surface. The double edged blade C is formed with centrally disposed notches G in its ends, and with end surfaces C at opposite sides of each notch (l'. The'blade is so proportioned relative to the holder that when inserted in the latter the two end surfaces C adjacent the then inactive or rear edge. of the blade will fit snugly against the adjacent sidesof the ears A thereby preventing the bladefrom movement in a direction parallel to its cutting edges. At the same time the ears A each fit snugly between the parallel sides of t'hecorresponding notch C, and thereby prevent movement of the blade in a direction transverse to its cutting edge. The ears A are formed with apertures receiving the trunnion-like extensions B formed on the plate clamping member B, which is thereby pivotally connected to themember A. The memberB comprises a flat body portion, the free edge of which engages an inserted blade adjacent the active or frontcutting edge of the latter, and an offsetportion shown as consisting of two lugs B which project to one side of the plane. of the body: portion of the clamping member and engage an inserted blade adjacent its rear or inactive edge. As the clamp is thrown from the open position shown in Fig. 4 into the closed position shown in Fig. 5, the free ends of the lugs B will pass between the axis of the trunnions B and the blade supporting surface A and the parts are so proportioned that the projections 13 will be under tension when in the closed position shown in Fig. 5, and, in eflect, form springs resiliently holding the clamping member B in the closed position.

It will be apparent without detailed explanation that the body member of my improved safety razor blade holder may be formed by simple manipulations out of the easily formed sheet metal blank (2, shown in plan in Fig. 1. All that is required to con- .vert the blank a into the holder body member A shown in Figs. 4 and 5, is to bend up the projecting portions forming the ears A and A, slightly bend the guard fingers A, and offset the elongated tang of the blank to form the handle and neck portions A and A Advantageously though not necessarily, the handle portion A is twisted into spiral form, as shown in Figs. 4 and 5. The

clamp B may obviously, be formed from the sheet metal blank I) of Fig. 2, by simply bending the portions forming the spring projections B away from the plane of the body portion of the clamp. It will be understood of course that in practice, the

trunnions B of the holder B will ordinarily formed of highly tempered steel of ribbonlike thickness, since sharp corners, such as it would be necessary to give the notches C to make the latter fit snugly against the inner flat sides of the lugs A as Well as against the edges of these lugs, are apt to cause cracks in the blades in the tempering of the latter.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A holder for a safety razor blade having notches formed in its ends, said holder emnprising a frame member formed with a blade supporting bed and with an opposed pair of ears at the ends of the latter adapted to enter the notches in the ends of a blade resting on said bed, and with a second opposed pair of ears at the ends of said bed adapted to engage the end surfaces ofthe inserted razor blade at one side of the notches thereof, and means for razor blade against said bed.

. 2.'In a safety razor, the combination of clamping aa blade having notches with rounded bottoms formed in its ends, and a blade holder comprising a frame'member formed with a bed on which the blade rests and'with an opposed pair of. ears entering the said notches and fitting between the sides thereof and thereby preventing movement of the blade in a direction transverse to its length and formed also with a second pair of ears engaging the end surfaces of the blade at one side of the notches thereof and thereby preventing movement of the blade in a dil rection parallel to its length, the parts being so proportioned that the first mentioned ears do not engage the rounded bottoms of the blade notches in which they enter.
